Faculty Profile

Qiang Zhu

Professor, Structural Engineering


Ocean engineering, biomechanics.

Professor Zhu’s research interest is in interdisciplinary investigations that combine offshore engineering and biomechanics. Correspondingly, his research includes two parts: (1) To apply established and well-tested theoretical and numerical tools in the field of civil/offshore engineering to study structural and fluid-structure interaction problems in biomechanics; (2) To utilize knowledge gathered from the structure vs. function of living creatures for biomimetic studies of novel mechanical, civil, and offshore structures. His current research focus are on mechanics of skeleton-reinforced biomembranes (including cell membrane and fish fins), flow energy harvester based on flapping foils, and fluid/structural modeling of floating wind turbines.

Capsule Bio:

After completing his PhD, Professor Zhu had worked as a postdoctoral researcher and a research engineer at MIT before joining UCSD. Zhu has published a variety of papers on his work involving fluid-structure dynamics problems.
